The Mercedes-AMG GT Roadster has been revealed ahead of a public debut at the Paris Motor Show, with the open-top two-seater coming with 469bhp.

But it’s not just a GT Roadster on offer, but a more powerful, and more comprehensively equipped, range topping model too – the 550bhp Mercedes AMG-GT C Roadster.

The entry-level AMG GT Roadster actually gets more power and torque than the coupe, and the GT C Roadster sits a bit below the GT R in terms of power with its 550bhp and 501lb/ft of torque.

The AMG GT Roadster’s 469bhp is enough to hit 62mph in 4.0 seconds and on to 188mph, and the GT C Roadster is three tenths quicker at 3.7 seconds and a top speed of 196mph, impressive figures considering both weigh a chunk more than the coupes despite a fabric folding roof.

Both the GT Roadsters get the advantage of some of the active aerodynamics from the GT R with louvres behind the grille controlling airflow, and the grille itself is a Panamerica 15 bar one from the GT3.

The GT C Roadster goes further still, with a wider track making it look like a GT R Roadster, and comes with active rear steering, electronic limited slip diff, adaptive dampers, race mode on the dual-clutch gearbox.

Both the Mercedes-AMG GT Roadster and GT C Roadster will get a public debut at the Paris Motor Show later this month, but aren’t expected to arrive in the UK until spring 2017 – just in time for some roadster weather.

As for prices, Mercedes aren’t saying. But around £110k for the AMG GT Roadster would seem about right, and perhaps around £120k for the GT C Roadster.
